Spots Global Cancer Trial Database for Neo-adjuvant Abiraterone + Luteinizing Hormone-Releasing Hormone (LHRH) Versus LHRH in Prostate Cancer

Study Description

Brief Summary: The goal of this clinical research study is to find out how treatment with abiraterone acetate in combination with prednisone and a Luteinizing Hormone-Releasing Hormone (LHRH) analogue changes the tumor in comparison to treatment with an LHRH analogue alone. Objectives: Primary Objective: To assess the difference in pathologic stage \< pT2 between Group A and Group B. Secondary Objective: * To assess and compare the changes in levels of androgens (pre, during, and post treatment) in the serum, primary tumor microenvironment and bone marrow between Group A and Group B. * To assess changes in biomarkers related to androgen signaling and other cancer-related pathways between Group A and Group B. * To assess the difference in rate of positive surgical margins between Group A and Group B. * To assess the safety profile of abiraterone acetate and low dose prednisone in a preoperative setting.

Detailed Description: Study Groups: Participants who are eligible to take part in this study will be randomly assigned (as in the flip of a coin) to 1 of 2 groups: * Those who are in Group A will take abiraterone acetate, a LHRH analogue, and prednisone. * Those who are in Group B will receive a LHRH analogue alone. Participants will have 2 out of 3 chances of being placed in Group A or 1 out of 3 chances of being placed in Group B. Participants in both groups will receive the study drug(s) for about 3 months followed by a prostatectomy (prostate surgery) between 2 and 4 weeks after they stop taking the study drug(s). Length of Study: Participants will receive study drugs on this study for about 3 months before having surgery to remove their prostate about 2-4 weeks later. Participants will be removed from this study if the disease gets worse, if they experience intolerable side effects, or their study doctors feel that it is in their best interest to stop the study. Long-Term Follow-Up: Participants will return to the clinic 1 month, 3 months, 6 months, and then every 6 months (for up to 8 years) after your surgery for follow-up visits. Up to 66 patients will be take part in this study. All will be enrolled at M. D. Anderson after their surgery.
